Production of X-Rays 来自 Springer 喜欢 0 阅读量: 14 作者: Ervin B. Podgoršak 摘要: This chapter deals mainly with production of x rays but it also provides a brief introduction to erenkov radiation and synchrotron radiation (magnetic bremsstrahlung). Two types of x ray are known: c...
OBSERVERS who use Wimshurst machines should remember that part of their difficulty in obtaining X-rays with a steady current and low vacuum may lie in a peculiarity of the machine itself, viz. that it will not work well when short-circuited. Machines with permanently charged armatures do not ...

A description is given of production of K fluorescent x-rays using an x-ray generator and secondary targets. Filtration was used to improve the spectral purity. Spectral measurements are presented for eight different target materials. The spectral purity in terms of photons and exposure are given....
The material is cut into slices in a direction parallel to the direction of the deposition of the two types of substances. The edge is fixed as a plate (4) of interference on the surface of a crystal (5) a dispersing agent in order to obtain a focusing device / dispersion to x-rays...
ACCORDING to recent work, X-ray-induced chromatid breaks in Tradescantia microspores are due to the simultaneous occurrence of about seventeen ionizations concentrated within the narrow section of a chromatid. Such clusters of ionizations can be produced by electrons with small kinetic energy, that ...
Do it in-house! I love having this much control over the look of my work and being able to audition Continuum on the spot. Bradinn FrenchEmmy Award-Winning Editor I use Mocha Pro all the time. So much of my job starts with tracking. If you get that wrong, then nothing is going to...
